This study was performed to investigate the contamination levels of harmful heavy metals that sampled from June. 1 to June. 31, 1999, at 3 areas in Jeonbuk west cost area. The heavy metal contents were determinated by ICPS (Inductively Coupled Plasma Spectrometer) method. The levels of total lead, cadmium, aluminum, zinc and copper were determined and the results were summarized as follows: The minimum and maximum values (ppm) of 3 areas of shellfishes (shortneck clam, hard clam, cockle clam, snail and top sell) were Pb: 1.29~4.35, Cd:0.12~0.37, Al: 9.45~54.06, Zn: 9.65~15.14, Cu: 0.62~1.64 ppm.
